Interesting - at least for Finland, biomass (aka wood), and oil are common for folks out in the sticks, and district heating and electric resistive or heat pumps are more common in settlements or cities.
My guess is the difference is due to infrastructure? Finland is widely dispersed, and it’s expensive to run pipelines for natural gas in frozen ground.
So something naturally present (wood), tankable/drivable (oil), or centralized in a settlement (district heat) wins? Similar with Norway and Sweden?
Russia is a bit different because it has a lot of oil and natural gas, but even then outside of a major city, probably wood wins?
Germany has a much milder climate, and is much denser, but not all centralized, and especially after the wars, centralized heating probably seems like a dangerous idea.
